DEVICE FOR SUPPRTING RADIO PARTS.

Application tiled April 30, 1924. Serial No. 710,204.

This invention relates to devices for supporting radio parts orapparatus in operative position. rected to a device for supporting suchradio parts as inductance coils and the like in definitely fixed orrequired relation.

An object of the invention is the provision of a device which permitsmounting the radio parts, such as an inductance coil in its exactrequired position, without necessitating the use of templates orparticular 'drilling of the panel for properly positioning such coil.

Another object of the invention is thc PTfvision of a device of thecharacter described for mounting a. radio part, such as an inductancecoil, at a definite angle or in definite relation to other parts of theapparatus and whereby the partmounted .is securely held at such angle orre-lative position.

A further object of the invention is to rovide a device of the characterdescribed which shall be exceedingly simple and cheap to manufacture,easy and quick to install, and efficient in operation to a. high degree.

Other objects of this invention will inV part be obvious and in parthereinafter pointed out.

The invention accordingly consists in the features of construction,combinations of elements and arrangement of parts which will beexemplified in the construction hereinafter described and of which thescope of application will be indicated in the following claims.

In the accompanying drawing, in which is shown one of the variouspossible illustrative embodiments of this invent-ion,

` Fig. 1 is an elevational view showing an embddiment of the inventionas employed for mount-ing thereon the coils of a neutrodyne radio set;

Fig. 2 is a perspective view of the supporting member embodying thisinvention for mounting the coil at a definite angle to the horizontal;

Fig. 3 is a perspective view of the base member on which one or moresupporting members such as shown in Fig. 2 may be mounted; and

Fig. 4 is a fragmentary view in side elevation of a mounting deviceshowing a modified form of interlocking between the supporting memberand the base member.

Referring in detail to the drawing, the supporting member for theinductance coil is in- More particularly, it is di-` dicated generallyat 10, and is seen to comprise a vertical'base portion 11, and asupporting or mounting portion 12 extending at a definite angletherefrom. Thus, where the supporting member 10 is to be employed with aneutro'dyne set, the angular relation of the portion 12 to the portion11 will be such that the angle included between the longitudinal axis X,X of the member 12 and the vertical axis Y, Y, of the member 10 will be35.5 degrecs so that a vertical plane passing through the axis of a coilmounted on member 11 will be at an angle of 54.7 degrees to thehorizontal, the angle required for proper inductive effect in theneutrodyne set.

The member 10 may be formed as a. unit from suitable insulating ornon-magnetic" material such as hard rubber composition, wood, and thelike, and may be either molded, cast, or cut into proper shape. Thematerial of the portion 12 is preferably cut away as at 12, sothatsubstantially litt-iematerial is interposed in the air space of thecoil 18 mounted thereon. This .eliminates ypossible interfering capacityeffects that mayA result from the insertion of any other sub1- stancethan air into the interior coil spacev and further reduces the cost ofthe supporting unit. The supporting unit 10 is preferably made flat andof sufficient thickness to give it the desired rigidity and strength. Itwill be understood, of course, that the portion 12 will be of such widthas to snugly fit the interior of the inductance coils 'when the same isplaced thereon.

To prevent possible displacement of the coil, I provide in the member10, between the portion 1.1 an'd 12, a notch or groove 14 of a widthsubstantially equal to the thickness of the tube or spool 13 of thecoil, so that when the coil is mounted on the supporting member, it titsover the portion 12 and into this groove 14 as will be readilyunderstood, thus being held firmly in position at the desired angle tothe horizontal.

Where one or more inductance coils or the like apparatus are to bemounted in parallel relation to each other, I provide a base inember 15,which may be secured in any desired position on the base board 16 of thepanel 17 on which the various apparatus is mounted. Thus, the basemember 15 may be provided with spaced openings 18 for screws or the likefastening members. A longitudinal groove or channel 19 is provided inthis base member 15 of a width substantially equal to the lthickness otthe portion ll of the supporting member l0, and of sufficient depth sothat when this portion 11 is inserted into the channel, it will befirmly held-therein.

VEhe base member l5 may likewise be made,

cast, or molded, or otherwise shaped from suitable insulating' ornonmagnetic material.

In the form shown in Fig. il, the channel and the base member is.dove-tailed in crosssection, and the portion 1l of the supportingmember l0 likewise of dove-tail shape. Qt' course, other modificationsmay readily occur to one slrilled in the art, and it will be understoodthat all matter herein set forth or shown in the accompanying drawingsis tofbe interpreted as illustrative and not in a limiting sense.

It WillV thus be seen that I have provided a very simple, neat,.andinexpensive device, Well adapted and etticient tor the purposes setforth, and which can be readily manufactured inv a simple and iinexpensive manner..

Having thus described my invention, I claim as new and` desire to secureby Letters Patent l. A supporting device ot the character describediformed- 'ot sheet material comprising a vertically extendingv baseportion and a coil mounting portion extending from the upper end ot'said base portion, the longitudinal axis. oft the coil mounting portionextending at less than 900 to the vertical axis of the baseportionsaidbase and coil mounting portion lying in the same plane.

2. A supporting device of the' character described termedo't sheetmaterial comprising a vertically extending base portion and a coilmounting portionextendingrom the upper end ot said base portion, thelongitudinal axis et' the coil mount-ing portion extending less than 9,o to the vertical axis ot the bare portion, an edge oil said base`portion being extended to iorn'i a notch with an edge of said coilmounting portion, said notch being adapted to receive and to retainagainst displacement a coil mounted on the latter portion.

3.' In Combination with a tubular-ly Wound tuning coil,.a mounting,device therefor comprising a vertically extending base` portion and acoil mounting portionextending from the upper vend ot said base portion,the longitudinal: airis ot th coil mounting portion extending at lessthan 90o to the vertical axis ofthe base portion, said mounting portionbeing of a Width substantially equal to the inner diameter ot the coil.

t. In combination with a tubularly Wound tuning coil, a mountingv devicetherefor comprising a vertically extending base portion and-a coilmounting portion extending trom the upper endA oit said buse portion,the longitudinal axis oi the coil mountino' portion extending at lessthan 900 to the vertical axis ot the portion, said mounting yportionbeingoit a Width substantially equal to the inner diameter ot thecoihsaid base portion being` extended along an edge thereolito torinanotch with an edge oliv said mounting portion, said notch beingpositioned to en gage the coil. mounted on the latter portieri forpreventing the displacement of the coil trom its mounted position.

In testimony whereof I aliix my signature.
